umm, i don't know where you heard about adding ferts and additives to root clones but all you need is water. distilled water is best but nothing more! that's all they need as most likely they came off of mother plants already well fertilized. i also have never heard of using super-thrive for rooting clones, let alone used as a foliar spray. save the s-t for transplanting along with everything else and stick with straight water and your mister next time you try it.

and you need the rooting solution...but that's it.
